  高中英语名词性从句的知识点

  一. 主语从句

  主语从句是在复合句中充当主语的从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。

  1. It 作形式主语和it引导强调句的比较

  It 作形式主语代替主语从句,主要是为了平衡句子结构,主语从句的连接词没有变化。而it引导的强调句则是对句子某一部分进行强调,无论强调的是什么成分,都可用连词that。被强调部分指人时也可用who/whom。例如:

  a) It is a pity that you didn’t go to see the film. 你不去看那场电影真可惜。

  b) It doesn’t interest me whether you succeed or not. 我对你成功与否不感兴趣。

  c) It is in the morning that the murder took place. 谋杀案是在早上发生的。(强调句型)

  d) It is John that broke the window. 是John打碎的窗户。(强调句型)
